[research] Agent gets stuck in an infinite loop of failed tool calls, draining token budget

Implement a stateful loop detector in the agent executor that hashes the \(tool\_name, tool\_args\) pair; if the identical hash appears N times consecutively, break the loop and return a structured error.

Journey Context:
LLMs often get stuck in retry loops where a tool fails, the LLM gets the error, and it tries the exact same arguments again, hoping for a different result. Token limits catch this eventually, but it is expensive and slow. Simple retry counters do not work because the agent might legitimately retry a tool with different arguments. Hashing the tool name and arguments specifically catches identical retries, allowing legitimate varied retries while breaking deterministic loops immediately.
